I've heard these are the best. Mine have the plates and I paid 90 euro with a pair of military dampers/isolation hoods, I guess I was very lucky ...
Hello yawg,
You've got three different "CCa siemens" - that I know

-:
- the halo getter with "two arms, bold label" that I have got,

- the halo getter with "one arm, thick label", better I have been told,
- the halo getter with "one arm thick label with grey shield between grey plates", the best of the bests I have been told; I hope so for more than 300 euros a pair...
And an outsider the "Siemens E188CC one arm with grey shield between grey plates", the best of the best E88CC...but very rare and too expensive IMHO...
yawg hat geschrieben:.../...Which other models of E88CC would you recommend to try out? Thanx!
You've got THE Ones, I think: but someone told me that 6922 Russian MP SLNM CRYO E88CC/6H23CRYO ones above were excellent as well...

If you need >100W, I am not sure that tubes power amps should be the ones unless very very expensive ones IMHO. But I have been told that very cheap Jungson JA-99C (80W class A) was excellent...
